I know I will probably get some slack for this but here it goes anyway:

If I read this right, I believe this is an "option" NOT a "requirement". I would assume that means that if you don't want you real name displayed, fine, choose the option for it NOT to display.

So what is the big deal? If anyone who has purchased something online, you had to enter you "real" name for billing purposes. And for anyone who thinks it's impossible to find out information about yourself, see more is completely clueless to just what information is available on the internet (IP traces, Whois, Email reverse lookups, etc.)

In the end, I think that its a good idea that you have at least given the option to opt out of this if the member chooses to.
